IMPROVEMENT IN- STENCH-TRAPS.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern.-

Be it known that l, JAMEsF. DACEY, of Charlestown,in the county ot' Middlesex, and State of Massachusetts, have invented an Improved stench-Trap; and 1 do hereby declare lthat the following, taken in connection with the drawings which accompany and form part of this specification, is a description of my invention, sufficient to enable those skilled in the art -to practise it.

The invention relates tothe construction of a stench-trap for sinks and wash-bowls, with reference to such arrangement of the outlet-pipe as shall bringr lthe trap into the smallest practical compass, to enable it to be readilyjitted to a bowl or outlet from a sink.

Stench-traps made like that shown in the accompanying drawing at c, are now to some extent in use, said ,trap consisting of a vertical body or chamber, a?,

vthe neck 1fl of which i's screwed to the under surface of the bowl by a hollow screw, c2, which extends through the outlet of the bowl, and receives the plug or stopper d".

In the chamber a2 is a partition, t, which divides off one side of the chamber, from which divided part leads the outlet e2, the partition extending not quite to the bottom of the chamber, and the passage under Ithe partition heilig below the level ot' the pipe f, leading from the outlet e'f while at the bottom of the chamber is a screw-plug, g2, by removal ot' which the solid sediment collected in the chamber can be at any time removed.

' Into the main chamber leads the overow-pipe h2, which runs from the upper part of the bowl.

Now the principal object oi' my invention is to so make a trap that the waste o1` outlet-pipe leads from the bottom ofthe chamber or body of the trap, instead of laterally therefrom, as shown at C; and it is in a stench-trap having within it two partit-ions, so arranged as to seal the outlet-pipe, said outlet-pipe leading vertically and directly from the trap, that my invention consists.

A stench-trap embodying the improvement is shown at A and B, in the drawings; at A, in the vertical cross-section, and at B in vertical longitudinal section.

c denotes the body of the trap, the neck b of which is fastened to the under side of the bowl by thel screwtube or coupling c, in which the stopper or plug tl is placed, this tube leading directly ti'om the bowlinto the main chamber cof't-he trap.

f is the overflow-tube, connected with the pipe which leads from the top of the bowl, this tube preferably entering the upper part of the chamber e, as seenatB.

From the bottom of the trap, in avertical line with the inlet-tube, leads the outlet-tube g, and between y "the outlet and inlet are' arranged partitions by which the outlet is kept sealed by water within the chamber e. These partitions are shown at h and 'L'. They extend cross-wise of the chamber, as seen at B.

The upper one h, springs from one wall, k, of the chamber, at the top thereof, and extends down aud over towards the opposite wall l, leaving a passage, m, under its bottom edge, as seen at A; and the lower partition i springs from -the wall 1, at the 'bottom thereof, and extends over towards the wall k, and up towards the partition h, leaving a passage, u, between its` upper edge and the partition t, said'upper edge being above the level oi' the lower edge of the partition h, as seen at A.

The water flowing from the bowl or sink has to pass down through the main chamber e, under the parti- I tion h, up between the partitions h t', and over the partition t', and thence down through an auxiliary chamber o into and through theoutlet g, into the drain-pipe; and the relative position ofthe edges ofthe two partitions keeps the chamber filled with water up to the level of the partition i, and above the level of the bottom of the partition h, thus sealing the trap at each edge.

On one side ofthe chamber e is an outlet, p, closed by a screw-plug, q, by removal of which the solid sediment settling to the bottom of the chamber can beremoved. A

1t will readily be seen that the improved trap can be applied in a very narrow space, no room being taken up except that in a direct vertical line with the wastepipe, so that in any place where a bowl can be set, with a waste-pipe leadingr from it, the trap can be used.

I claim a stench-trap, constructed .with the partitions t and i, outlet g, outlet p, and screw-plug q, relatively arranged, substantially as shown and described.

Also, the combination, with partitions h and i, when arranged as above set forth, of the overow-pipe f, arranged as vshown and described.
